# SMTP Rake tasks
DETAILS:
**Tier:** Free, Premium, Ultimate
**Offering:** Self-managed
The following are SMTP-related Rake tasks.
## Secrets
GitLab can use SMTP configuration secrets to read from an encrypted file. The following Rake tasks are provided for updating the contents of the encrypted file.
### Show secret
Show the contents of the current SMTP secrets.
- Linux package installations:
```shell
sudo gitlab-rake gitlab:smtp:secret:show
```
- Self-compiled installations:
```shell
bundle exec rake gitlab:smtp:secret:show RAILS_ENV=production
```
**Example output:**
```plaintext
password: '123'
user_name: 'gitlab-inst'
```
### Edit secret
Opens the secret contents in your editor, and writes the resulting content to the encrypted secret file when you exit.
- Linux package installations:
```shell
sudo gitlab-rake gitlab:smtp:secret:edit EDITOR=vim
```
- Self-compiled installations:
```shell
bundle exec rake gitlab:smtp:secret:edit RAILS_ENV=production EDITOR=vim
```
### Write raw secret
Write new secret content by providing it on `STDIN`.
- Linux package installations:
```shell
echo -e "password: '123'" | sudo gitlab-rake gitlab:smtp:secret:write
```
- Self-compiled installations:
```shell
echo -e "password: '123'" | bundle exec rake gitlab:smtp:secret:write RAILS_ENV=production
```
### Secrets examples
**Editor example**
The write task can be used in cases where the edit command does not work with your editor:
```shell
# Write the existing secret to a plaintext file
sudo gitlab-rake gitlab:smtp:secret:show > smtp.yaml
# Edit the smtp file in your editor
...
# Re-encrypt the file
cat smtp.yaml | sudo gitlab-rake gitlab:smtp:secret:write
# Remove the plaintext file
rm smtp.yaml
```
**KMS integration example**
It can also be used as a receiving application for content encrypted with a KMS:
```shell
gcloud kms decrypt --key my-key --keyring my-test-kms --plaintext-file=- --ciphertext-file=my-file --location=us-west1 | sudo gitlab-rake gitlab:smtp:secret:write
```
**Google Cloud secret integration example**
It can also be used as a receiving application for secrets out of Google Cloud:
```shell
gcloud secrets versions access latest --secret="my-test-secret" > $1 | sudo gitlab-rake gitlab:smtp:secret:write
```
